Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Batch Gradient Descent is the only optimization algorithm for AI models. | While Batch Gradient Descent is a popular optimization algorithm, there are other algorithms such as Stochastic Gradient Descent and Mini-Batch Gradient Descent that can also be used to optimize AI models. It’s important to choose the right algorithm based on the specific requirements of your model. |
| Increasing batch size always leads to better results. | Increasing batch size can lead to faster convergence but it may not necessarily result in better performance or accuracy of the model. In fact, larger batch sizes can sometimes lead to overfitting and slower training times due to memory constraints. The optimal batch size depends on various factors such as dataset size, complexity of the model, available hardware resources etc., and should be determined through experimentation. |
| Using a high learning rate will always speed up training time without affecting accuracy negatively. | A high learning rate can cause overshooting which means that instead of converging towards an optimal solution, it oscillates around it or diverges completely leading to poor performance or even failure of the model altogether. Therefore, choosing an appropriate learning rate is crucial for successful training and this requires careful tuning through trial-and-error methods like grid search or random search techniques. |
| Overfitting occurs when using Batch Gradient Descent. | Overfitting occurs when a machine learning model learns too much from its training data resulting in poor generalization ability i.e., inability to perform well on unseen data points outside its training set distribution boundaries (out-of-sample). This issue is not unique to Batch Gradient descent alone but rather affects all machine learning algorithms including deep neural networks trained with SGD variants like Adam optimizer etc.. To avoid overfitting one needs regularization techniques like L1/L2 weight decay penalties or dropout layers during network architecture design phase itself along with early stopping criteria based on validation set performance. |
| Batch Gradient Descent is only suitable for small datasets. | While it’s true that Batch Gradient Descent can be computationally expensive and memory-intensive when dealing with large datasets, there are ways to mitigate this issue such as using distributed computing frameworks like Apache Spark or TensorFlow on GPUs/TPUs which allow parallel processing of data across multiple nodes/machines. Additionally, one can also use techniques like data sampling or feature engineering to reduce the size of the dataset without losing important information needed for training the model effectively. |
